Question 1: Palatine bone

Answer:

a bone of extremely irregular form on each side of the skull that is situated in the posterior part of the nasal cavity between the maxilla and the pterygoid process of the sphenoid bone and that consists of a horizontal plate which joins the bone of the opposite side and forms the back part of the hard palate and a vertical plate which is extended into three processes and helps to form the floor of the orbit, the outer wall of the nasal cavity, and several adjoining parts called also palate bone palatine. One of two irregularly shaped bones (L-shaped) forming the posterior part of the hard palate, the lateral wall of the nasal fossa between the medial pterygoid plate and the maxilla, and the posterior part of the floor of the orbit. The posterior part of the hard palate, which separates the nasal cavity from the oral cavity, is formed by the horizontal plates.

Answer:

Answer:

The sphenoid bone (from Greek sphenoeides, "wedgelike") is an unpaired bone situated at the base of the skull in front of the temporal bone and basilar part of the occipital bone. The sphenoid bone is one of the seven bones that articulate to form the orbit. Its shape somewhat resembles that of a butterfly or bat with its wings extended.
